A refugee is a person who is outside their country of origin or habitual residence because they have suffered (or fear) persecution on account of race, religion, nationality, political opinion, or because they are a member of a persecuted ‘social group’ or because they are fleeing natural disaster. Such a person may be referred to as an ‘asylum seeker’ until recognized by the state where they make a claim.
Throughout human history, there have been regular times where large numbers of people have had to seek refuge away from their traditional homes. The situation is very difficult for the refugee. They are among strangers who often use and abuse them. God told His children through Isaiah that they should provide shelter to Moabites. And this was one of the people groups the Israelites often fought!
